The National Energy Board investigates how a natural gas pipeline, operated by Enbridge, ruptured and created an explosion on Tuesday night. Sarah MacDonald reports.

The investigation into what caused a natural gas transmission pipeline owned and operated by energy giant Enbridge has been elevated from a regional to a provincial level, officials confirmed to Global BC on Wednesday.

The BC RCMP are now taking over what will be a lengthy and complicated investigation, due to what officials are calling its “potential scope and scale,” if the explosion is ultimately deemed to be a criminal matter—or one involving terrorism.

But Spraggs said she simply feels fortunate to still have her house intact. The blast, which occurred not far from her house, shook the house’s frame, and Spraggs said she was surprised her windows didn’t break.

“I’m thinking there might be a run on electric stoves, and electric heaters,” Spraggs added. And she could be right.

Fortis BC made an unprecedented appeal to its customers, in light of the gas line explosion, to scale back on their use of natural gas early Wednesday.

None of the company’s infrastructure was damaged in the explosion, though it relies on the line that was ruptured to serve its customers. That line is now out of commission for an indeterminate amount of time.

Enbridge officials say they have no definitive timeline on the reparations of that ruptured pipeline, noting their crews are having difficulty accessing the area of the blast due to hot spots, as debate rages over the issue of pipelines, and their safety in this province.
